you are right charges can never be at rest but the columbs law and electric field and other topics are being studied just imaginary, suppose that when charges are at rest they must emit a field which is called as electric field.
current is produced.
An electric current is produced when charges are accelerated by an electric field and move to a position of potential energy difference. This movement of charges generates a flow of electric charge that constitutes an electric current.

When charges move along a path, an electric current is produced. This flow of electric charge can result in the generation of a magnetic field around the path of the moving charges. The relationship between electric current and magnetic fields is described by the laws of electromagnetism.
When an object becomes charged, the plus and minus charges are only separated. No new charges are created in the process. The redistribution of existing charges within the object results in a net charge, giving the appearance of charge production.

One can induce a static charge by rubbing two objects together, causing the transfer of electrons between them and creating an imbalance of positive and negative charges.
Current is produced when charges are accelerated by an electric field to move to a position of lower energy.
The anode produces positive charges, while the cathode produces negative charges.
Electric fields are created by electric charges and exert forces on other charges, while magnetic fields are created by moving electric charges and exert forces on other moving charges. In summary, electric fields are produced by stationary charges, while magnetic fields are produced by moving charges.
Faraday says you will induce a current in the wire.
Yes, a changing magnetic field will induce an electric field, leading to the movement of electric charges. This phenomenon is described by Faraday's law of electromagnetic induction.
Charged objects can induce a charge separation in neutral objects through the process of polarization, where the charges within the neutral object temporarily redistribute. This redistribution of charges can cause the neutral object to be attracted or repelled by the charged object.

In electrostatics, we study charges at rest because the behavior of charges in motion falls under the purview of electrodynamics. Charges in motion create magnetic fields and induce electric fields, complicating the analysis that is simplified when charges are at rest. By focusing on charges at rest, we can better understand and apply fundamental principles of electrostatics.
Electric fields are created by electric charges and exert forces on other charges, while magnetic fields are created by moving electric charges and exert forces on moving charges. Electric fields are produced by stationary charges, while magnetic fields are produced by moving charges. Additionally, electric fields can be shielded by conductive materials, while magnetic fields can penetrate most materials.
